[PATCH 12/12] tty: drop termiox user definitions

From: Jiri Slaby
Date: Tue Jan 05 2021 - 07:04:31 EST


As was concluded in a follow-up discussion of commit e0efb3168d34 (tty:
Remove dead termiox code) [1], termiox ioctls never worked, so there is
barely anyone using this interface. We can safely remove the user
definitions for this never adopted interface.
